WebThe Hall-Heroult electrolytic process that has been developed in the late 19th century still forms the cornerstone of the aluminum production process. Most of today’s aluminum production facilities use carbon anodes that are dipped into an iron vessel or ‘pot’ (that functions as a cathode) that contains cryolite and alumina. ... WebH. Roustan. Aluminium is produced according with the Hall-Heroult process. During this complex electrolyte two-phase electrolysis, it is difficult to model the current distribution and to optimize ...
